ICE 1302;.

Application filed March 21, 1923. Serial No. 626,696.

To all whom it may concern Be it known that we, EDWARD R. STEEL and PETER C. MoLeARD, citizens of the United States, residing at Grundy Center and Eldora, in the counties of Grundy and Hardin and State of Iowa, have invented certain new and useful Improvements in Ice Boxes, of which the following is a specification.

Our invention relates to improvements in ice boxes, specifically adapted for the storage of serum, virus and other perishable vaccines, the nature of the invention being such as to maintain these elements at a uniform temperature, it being herein well to note that in extremely cold weather, the box is well adapted for maintaining these elements at a body temperature, and to prevent the freezing thereof in the act of transportation.

A further object of our invention resides in the provision of such an ice box that is of comparatively simple construction, extremely inexpensive of manufacture, and well adapted for the purposes intended.

Other objects of the invention will become apparent as the nature of the same is better understood from the accompanying drawings and specification.

In the drawings forming part of this application, like numerals of reference indi cate similar parts in the several views, and wherein Figure 1-is a perspective of a box con structed in accordance with our invention.

Figure 2-is a detail cross sectional view thereof, and

Figure 3is a perspective of the ice or hot water receptacle forming a component part of the present invention.

Referring to the drawings in detail, our box is preferably of oblong shape, it being of course understood that we do not wish to limit ourselves to such a specific shape as the design thereof may be changed to suit different requirements.

The box, per se, embodies an outer wall 5, and an interior wall 7, each of the same consisting of galvanized sheet steel. The outer wall 5 is formed with a bottom 5, spaced slightly above the edges thereof, whilst the interior wall 7 is formed with an integral bottom wall 9. From a consideration of the detail cross sectional view, Figure 2, it will be noticed that the upper edge, of the interior wall 7 is spaced a distance inwardly'of the upper edge of said outer wall 5, the upper edge of said interior wall 7 extending forwardly, and thence being bent upwardly and soldered, welded or otherwise secured to the edge of said outer wall. The box is provided with an exterior bottom wall 10, preferably of wood, the same being secured within the lower edge of the said galvanized sheet steel wall 5, through the instrumentality of nails, tacks or the like 11. Inside the outer wall 5 is a lining of corrugated cardboard 12, it being also noted that upon the said ooden bottom wall 10, is a galvanized sheet steel lining 5 upon which is a lining of corrugated cardboard, similar to the lin- Iiwetween the said corrugated cardboard and interior walls of the box is a filler 13 of mineral wool or other suitable insulating material, which is preferably in the form of a powder, the same being compressed between the cardboard and interior walls. Hingedly secured to the upper rear edge of the box as at 15 is a cover designated in general 16, this cover being of such dimensions as to engage within the said outer wall 5 of the box for support upon the upper edges of the said interior wall. This cover 16 embodies an outer wall 17, and an interior wall 18, and each of the same also consisting of of glvanized sheet steel. Inside the outer wall is a lining of corrugated cardboard 20, similar in all respects to the before mentioned card board lining 12. Between the interior wall and cardboard is a packing of mineral wool 21, or other suitable insulating material, the same being also preferably of powder form.

Hingedly secured as at 22 to a bracket plate 23 upon the front free end of the cover 16 is a hasp 24, the same being formed with a slot for engagement over an eye 25, for the purpose of receiving the, usual shackle of a padlock.

The sides of the box are formed integrally with handles 26, and adapted for disposition within the interior of the box, is a receptacle 27, also of galvanized sheet steel and'ada-pted for the reception of ice or hot water.

In view of the above description, it will be readily appreciated that in the transpor tation of serum, virus, or vaccines in warm weather, the said receptacle 27 is filled with ice for maintaining these elements at a low temperature, it being understood however, that should it ever-be desirable to maintain these elements at a body temperature, the said receptacle 27 may be filled with Warm Water, or if desirable receive a hot Water bag.

Other advantages of our device Will be readily appreciated by those skilled in the art, and although We have herein shown and described the preferred embodiment of our invention, it is nevertheless to be understood that minor changes may be made therein, Without departing from the spirit and scope of the invention as claimed.

Having thus described our invention, What We claim as new, and desire to secure by Letters Patent, is:

In a box of the class described including an inner and outer wall of galvanized sheet steel, a corrugated cardboard lining inside said outer Wall, and a packing of mineral Wool between said cardboard and said inner Wall.

In testimony whereof We afliX our signatures.

EDWARD R. STEEL. PETER C. MOLGARD.
